There are only a few studies about the prevalence and correlates of premature ejaculation (PE) among men who have sex with men (MSM).
(1) To estimate PE prevalence according to 3 assessment methods: self-reported time from penetration to ejaculation (ejaculation latency time [ELT]); Premature Ejaculation Diagnostic Tool (PEDT); and a direct question about the self-perception of ejaculation as being normal, too early (premature), or retarded. (2) To assess the agreement of the 3 assessment methods and identify factors associated with PE according to each method and their combination.
We evaluated data from 226 MSM who participated in a cross-sectional study about sexual behavior among men living in the metropolitan region of São Paulo, Brazil. They responded anonymously to an online survey between May 2019 and March 2020. We calculated the agreement of the 3 assessment methods and their association with other characteristics using logistic regression models.
Outcomes included the prevalence of PE according to the assessment methods and the association measures (PE vs sociodemographic characteristics and sexual behavior).
The prevalence of PE among MSM was 21.2% (95% CI, 16.1%-27.1%) according to the PEDT, 17.3% (95% CI, 12.6%-22.8%) per self-report, and 6.2% (95% CI, 3.4%-10.2%) by estimated ELT ≤2 minutes. The agreement among the 3 assessments was fair (kappa, 0.31; 95% CI, 0.25-0.37; < .001). Association with PE varied by assessment method: obesity and shorter time for ejaculation with anal sex vs masturbation were associated with PE according to the PEDT and ELT but not self-evaluation. Perception about ideal time to ejaculate ≤5 minutes increased the chance of PE based on ELT. Higher chances of self-reported PE were associated with trying to hold back ejaculation, and lower chances were associated with higher frequencies of masturbation.
Combining tools to investigate PE allows the identification of characteristics associated with this condition and may result in improvement in the care of MSM.
This anonymous online survey provided the privacy necessary for participants to respond freely about sensitive questions, with a low risk of social adequacy bias. However, as it was a secondary analysis of a larger study, it could not evaluate comorbidities (eg, erectile dysfunction, prostatitis, depression) and the use of condoms.
The prevalence of PE among MSM is high and varies according to the instrument used for the assessment, and the agreement among the 3 assessments was only fair.
关于男男性行为者（MSM）中早泄（PE）的患病率及其相关因素的研究较少。
（1）根据三种评估方法估计早泄患病率：自我报告的从插入到射精的时间（射精潜伏期[ELT]）；早泄诊断工具（PEDT）；以及一个关于射精自我认知是正常、过早（早泄）还是延迟的直接问题。（2）评估这三种评估方法的一致性，并根据每种方法及其组合确定与早泄相关的因素。
我们评估了226名参与巴西圣保罗大都市区男性性行为横断面研究的男男性行为者的数据。他们在2019年5月至2020年3月期间对一项在线调查进行了匿名回复。我们使用逻辑回归模型计算了这三种评估方法的一致性及其与其他特征的关联。
根据PEDT，男男性行为者中早泄的患病率为21.2%（95%CI，16.1%-27.1%），自我报告的患病率为17.3%（95%CI，12.6%-22.8%），估计ELT≤2分钟时的患病率为6.2%（95%CI，3.4%-10.2%）。这三种评估之间的一致性为中等（kappa，0.31；95%CI，0.25-0.37；<0.001）。与早泄的关联因评估方法而异：根据PEDT和ELT，肥胖以及肛交与手淫射精时间较短与早泄相关，但自我评估则不然。基于ELT，对理想射精时间≤5分钟的认知增加了早泄的可能性。自我报告早泄的较高可能性与试图抑制射精有关，而较低可能性与较高的手淫频率有关。
结合多种工具来调查早泄有助于识别与该疾病相关的特征，并可能改善对男男性行为者的护理。
这项匿名在线调查为参与者自由回答敏感问题提供了必要的隐私，社会适应性偏差风险较低。然而，由于这是对一项更大规模研究的二次分析，它无法评估合并症（如勃起功能障碍、前列腺炎、抑郁症）和避孕套的使用情况。
男男性行为者中早泄的患病率较高，且因用于评估的工具而异，这三种评估之间的一致性仅为中等。
